HYDROGARBON-GAS BURNER.

Specification of Letters Patent. Patented J an, 17, 1922,

Application filed September 12, 1919. Serial No. 323,382.

To all whom it may concern:

Be it known that I, CHARLES L. TORREY, a citizen of the United States, and a resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Hydrocarbon-Gas Burners, of which the following is a specification.

My invention relates to a device for reducing a suitable liquid hydrocarbon to a gaseous form and then properly distributing the same to prepared outlets for burning.

It is the object of my invention to provide a device of the character indicated which will be simple and eflicient in operation and which is provided with a novel form of discharge valve mechanism and connec tions whereby certain superior results are obtained.

In the drawing:-

Figure 1 is a plan view of the device embodying my invention, partly in section and part broken away.

Figure 2 is a front elevation of the gas generating portion of the device.

Referring more particularly to the drawing, 1-1 indicate a pair of burners to be used in the fire-box of a stove, and 2 is a third burner to be used in heating the stove oven, the three burners being joined to a casing 3 by means of conduits 4-5 and 6 respectively. Casing 3 is provided with an inlet chamber 7 and is divided into chambers 8-9 and 10 communicating with inlet 7 by means of valves 1112 and 13 respectively, chamber 8 also communicating with conduit 4, chamber 9 with conduit 5 and chamber 10 with conduit 6 as shown.

At 14 is shown a fuel supply pipe having a controlling valve at 15 and having a member 16 fitted therein. I here show an electric heater 17 fitted to pipe 14 at a point in which member 16 is fitted. Pipe 14 discharges into mixing chamber 18 provided with air inlet 19 and also, on its lower portion, with a plurality of orifices 20 positioned directly under pipe 14.

In use, if one burner as 1 is to be used the electric current is turned into heater 17 valve 11 is pushed open to the position 11", and valve 15 is opened sufficiently to permit the entrance of fuel oil into pipe 14 where it is rapidly broken up by the heat from heater 17 and mixed with air in mixing chamber 18. From the mixing chamber 18 the gas passes around through chamber 8 and conduit 4 to burner 1 where it is consumed. When the device is once started the gas is lighted at orifices 20 so as to supply the required heat to pipe 14, and the electric heater 17 is disconnected. Since all of chambers 89 and 10 have valve connections with inlet chamber 7 any of the three burners may be used when desired. If two or more are used then the increased flow of gas is effected by a further opening of valve 15.

The construction of this device in the manner hereinbefore described materially increases its efliciency since the gas is forced to circulate in chamber 7, is then forced through a small valve opening into another chamber as 8 where a further circulation takes place before it is finally passed to the discharge orifices in burner 1. This forced circulation through chambers and passages of varying size necessarily causes a series of changing velocities thereby so thoroughly mixing the gas and air that a clean clear flame is secured with practically no carbon deposit.

This construction also affords a cheap and efiicient method of distributing the gas as desired. If burner element 1 is in use with a heavy flow of gas, valve 12 may be thrown open' and both elements 1 and 1 used with a reduced flow of gas to each without changing the flow of oil through valve 15. Also during periods when the burners are not in use the flow of oil through valve 15 may be throttled down so that Just enough gas is generated to supply orifices 20 thereby maintaining the generator in operation and providing a pilot light so that any or all of the burner elements may be quickly brought into use.

In the embodiment shown the valves 11-12 and 13 are without springs and are manually operated in both directions, the gas pressure being sufiicient to properly seat the closed valves after they are closed by hand.

It is understood of course that changes in form, proportions, construction and method of operation may be made within the scope of the appended claim.

I claim:

A gas heater com rising a plurality of burners, a casing ha ing a like number of compartments, one for each burner, and a ma n} inlet chamber commun catlng with individual burner chambers a--sep arate valve for each burner compartment for controlling the communication between the latter and the main chamber a goose-neck mixing chamber connecting with the mainchamher and extending upwardly and backwardly overthe underlying portion, and a feed pipe connected with the overlying portion of the mixing chamber, said underlying portion having free and uninterrupted communicatien with the feed pipe and being formed directly beneath the latter with a plurality of orifices for providing a generating flame.
